IAR startup code (nrf5340 and nrf9160)

From our experience, Nordic's register setup is a bit different than the usual ARM cores, which requires some basic examples to get used to. Hence it is a massive pity that there are no baremetal examples available, only unnecessarily complicated Zephyr examples.

Nonetheless, we have managed to get the IAR startup files working and have marked this answer as verified.

Unfortunately, we do not have any bare metal implementation examples.

Thanks, it does not seem as if the GCC distribution includes these startup files. I have however managed to run the IAR installer, and found the startup files with the IAR Embedded Workbench directory.

That thus answers my main question.

Could you possibly refer me to a baremetal example project within VS Code/SES, where Zephyr is not included?

Hi,

Sorry. I have to correct my answer after confirming with the team. I am not aware the status is changing.

It's very possible to develop on nRF53/nRF91 devices without zephyr support. Our IAR installers include support for these devices, and the GCC distribution should include the IAR startup files as well. They're typically named iar_startup_nrf5340_application.s etc.

Sorry for the mislead again.

Amanda,

Let me try to be more explicit in my questions.

Why is this stated?

Is it possible to develop on a baremetal application WITHOUT Zephyr?

Unfortunately, we don't support for IAR.

Thanks, any chance you can answer the other questions as well?

Hi Amanda,

I find this very confusing. According to the MDK, https://www.nordicsemi.com/Products/Development-tools/nRF-MDK?lang=en#infotabs, IAR is supported. Also from within IAR Embedded Workbench, we are able to selected the nrf9160 and 5340 as target devices. We are also able to program and debug?

Also when using Segger or VS code, it seems as if the Nordic plugins force us to use to use Zephyr, which we do not plan on doing. Is this the case? There are no bare-metal examples.

Are there plans to get IAR supported?

Hi,

Unfortunately, IAR has not been supported for nRF5340 and nRF9160. I would suggest to Segger or VS code to build and debug. Sorry for the inconvenience.

Regards,
Amanda
